Abstract
A digital transmission apparatus having a base unit constructed in such a manner that n-bit digital signals transmitted from a plurality of (N) remote units are extended into (n+logN) bits in corresponding bit extending units, with respect to an addition result in an adding unit, an arithmetic operation of (2−1)/|addition result| is executed in a gain arithmetic operating unit, when an arithmetic operation result is smaller than '1', the arithmetic operation result is set into a gain coefficient, when the arithmetic operation result is equal to or larger than '1', “1” is set into the gain coefficient, further, the addition result is multiplied by the gain in a multiplying unit, and a bit contraction for discarding upper logN bits excluding a sign bit and returning to n bits is executed in a bit contracting unit.
